Housing & Infrastructure in Agar
With 79% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.

Housing Age Profile
Federal plumbing rules changed in two stages - lead pipes were phased out before 1970, and lead solder was banned in 1986 - but in Agar, where the median build year is 1901, most of the housing was already in place before those rules took effect. The materials installed under older standards remain embedded in a substantial portion of the residential inventory today.
Over half of homes in Agar were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Agar Homeowners
While Agar homeowners face a manageable path to remediation, the equity share sits in the moderate tier - a signal that proactive budgeting matters more here than in lower-ratio markets.
Remediation costs are moderate relative to home values in Agar. The estimated $800–$1,500 range is manageable for most homeowners but still worth budgeting for. Home values are 35% below the South Dakota average.
Lead Exposure Risk for Children in Agar
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Households with kids in the home - for whom CDC guidance places particular weight on minimizing exposure - face a specific local picture in Agar. 79% of homes here come from the pre-rule era, and aggregate utility samples either approach or cross 0.015 mg/L. A baseline draw-test kit and certified lead-removal filtration are available via retailer networks for households confirming conditions at a specific tap.
